ABSTRACT: Love could be one of the factors affecting on human happiness. Love (love others) and narcissism (self-love) could have a special relationship. This study aims to analyze the relationship between Love, Subjective well-being, and Narcissism, taking into account some of the cultural characteristics of Vietnam. The survey was conducted on 543 people aged from 19 to 40 years (M = 27.8; SD = 6.5), included 369 women (67.5%), 251 married people (46%). Love was measured using the Sternberg Love Scale [11]; Subjective well-being were measured by the Mental Health Continuum—Short Form [15]; Agentic narcissism was measured by the Narcissistic Personality Inventory [6]. The marital status was included in the study for comparison purpose. The results showed that Love and Narcissism do not have the significant correlation, while Love and Narcissism were positively correlated to the Subjective well-being. These positive correlations were higher among the married people. On average, Narcissism of married people was lower, while Love and Subjective well-being of married people was higher than that of the unmarried people. The paper also discusses about the positive correlation between subjective well-being and narcissism, and the positive effect of marriage on love and happiness of Vietnamese people.
